Sex still hurts, 5 months PP

Just wanted to see if what I’m feeling is normal or if I should go to the doctor. Sorry in advance for talking about my vagina in detail! 😂

I’m 5 months postpartum, I’m EBF, my period hasn’t come yet. I had a vaginal birth with a first degree internal tear that didn’t need stitches. The lower part of my vagina, closest to my perineum, feels thick and tight, and it’s a bit sore if I touch it. It doesn’t bother me day to day, but it hurts to have sex.

Anyone know what’s going on? Is this just normal healing or is this weird?
